Abstract
A combined output driver for TMDS signals and LVDS signals. First and second output drivers output first and second differential signals to a first external input unit and a second external input unit, respectively, through a pair of signal lines according to first and second input signals. In the second output driver, a driver buffer is coupled to a first voltage and a first node respectively to generate two control signals according to the second input signals. An output unit generates the second differential signal according to the two control signals. A power supply provides a second voltage higher than the first voltage to power the driver buffer and the output unit when the first output driver outputs the first differential signal to the first external input unit.
